The highly illustrated, heartwarming story of conservation heroes, dog Ajax and his handler Corey, who traverse remote parts of the South Island tracking kea nests.
Together, Corey and Ajax travel through the steep high country throughout the South Island searching out kea nests. Their part in the kea conservation effort is essential and both Ajax and Corey can rightly be called conservation heroes.
This heart-warming story describes how Ajax was trained to be one of the very few kea detection dogs in the world and tells of his various escapades in the unpredictable wilds of the steep back-country, including flying in helicopters; working in blizzards, heavy rain, and dense fog; escaping from angry wasps; and sleeping out in the bitter cold.
The strong connection between Ajax and Corey has proved vital to their survival and the important work that they do. Ajax is slowing down now and soon his high-country days will be over.

Most mountains on Earth occur within relatively well-defined, narrow belts separated by wide expanses of much lower-lying ground. Their distribution is not random but is caused by the now well-understood geological processes of plate tectonics. Some mountains mark the site of a former plate collision – where one continental plate has ridden up over another, resulting in a zone of highly deformed and elevated rocks. Others are essentially volcanic in origin.
The most obvious mountain belts today – the Himalayas, the Alps and the Andes, for example - are situated at currently active plate boundaries. Others, such as the Caledonian mountains of the British Isles and Scandinavia, are the product of a plate collision that happened far in the geological past and have no present relationship to a plate boundary. These are much lower, with a generally gentler relief, worn down through millennia of erosion. The presently active mountain belts are arranged in three separate systems: the Alpine-Himalayan ranges, the circum-Pacific belt and the mid-ocean ridges. Much of the Alpine-Himalayan belt is relatively well known, but large parts of the circum-Pacific and ocean-ridge systems are not nearly as familiar, but contain equally impressive mountain ranges despite large parts being partly or wholly submerged.
This book takes the reader along the active mountain systems explaining how plate tectonic processes have shaped them, then looks more briefly at some of the older mountain systems whose tectonic origins are more obscure. It is aimed at those with an interest in mountains and in developing an understanding of the geological processes that create them.

This second edition of Climate Change is an accessible and comprehensive guide to the science behind global warming. Exquisitely illustrated, the text is geared toward students at a variety of levels. Edmond A. Mathez and Jason E. Smerdon provide a broad, informative introduction to the science that underlies our understanding of the climate system and the effects of human activity on the warming of our planet.
Mathez and Smerdon describe the roles that the atmosphere and ocean play in our climate, introduce the concept of radiation balance, and explain climate changes that occurred in the past. They also detail the human activities that influence the climate, such as greenhouse gas and aerosol emissions and deforestation, as well as the effects of natural phenomena. Climate Change concludes with a look toward the future, discussing climate model projections, exploring the economic and technological realities of energy production, and presenting a view of the global warming challenge through the lens of risk. Each chapter features profiles of scientists who advanced our understanding of the material discussed. This new edition expands on the first edition’s presentation of scientific concepts, making it ideal for classroom use for a wide swath of undergraduate and masters students with both science and nonscience backgrounds.
